English is not my native language, but I will try to express my opinion, even if it is similar to what has already been said.
Estimating how many sponsors you had and that you have a team to develop the game, not just you alone, you could release updates for more. If you really appreciated your sponsors. But from the side it is clear that they deliberately delayed and this is understandable. Everyone wants a lot of money, for a minimum of work.
You have already offered a lot of option. You could just remake the beginning of the game, and in the remaining scenes only the text that Max is not the son of Anne. And instead of completing all the storylines, you decided to start a new game, more accurately transfer the old, also not completed. And there I am sure you will milk money too. And when the entire storyline goes too far, you will find a way to stop and start something new.
Digital game, this is not a real thing, not as a drug, it can be changed.
If you were alone, without a team, then you could be admired, now, you are throwing everything. I hope you do not do this with Glamor. Otherwise you will be the signs, but in a different direction.
